Abstract
Disclosed are systems and methods for peer-to-peer communication over a network between a first node behind a first network address translator (NAT) and a second node behind a second NAT, despite the first NAT and the second NAT intervening between the first and second nodes. The first NAT is a Symmetric NAT. A port prediction is performed wherein the first node constructs a list of predicted transport addresses on the first NAT. A message containing the list of predicted transport addresses is sent from the first node to the second node. A connectivity check is performed with the second node using the predicted transport addresses.
